Unrooted radial bootstrapped tree for NAP-like proteins based on PHYLIP analyses using Arabidopsis AtNAP (UniProt NP_564966) as the reference sequence. Representative genera are shown, together with E values, indicating the numerical expectation that the alignment with the reference sequence has arisen by chance. Support values (in red) were determined by bootstrap analysis (Additional file 1f). Branch lengths are proportional to number of amino acid substitutions per position. Additional file 2f gives branch length values and confidence limits from the PROML outfile.
